Samsung electric (NE58, NE59, NX58, NX60, Chef Collection) and gas (NX58H, NX58K, NX58T) ovens — including Flex Duo split-cavity models — fail to heat from element, sensor, igniter, door lock, or main board issues. Flex Duo adds an extra divider sensor.

Quick answer
Samsung ovens fail to heat in this order: (1) bake element open (electric NE / NX) or weak igniter (gas), (2) oven sensor drifted (preheats but never reaches temp, or E-0A / E-0E codes), (3) door lock motor failed (won't release after self-clean or won't permit bake), (4) Flex Duo divider sensor wrong (split-cavity reports wrong temp), (5) main control board element-relay failed. Most repairs land $285–$485 all-in. Flat $149 trip fee waived on approval. 1-year warranty.
Root causes, ranked by what we find
What it is: Element burns through, often at the back-right elbow. No glow on preheat. Ohms open on the meter.
Fix: Replace OEM bake element, verify amp draw and visible glow on preheat.
Typical all-in: $285–$385 all-in
What it is: Igniter glows but doesn't pull enough current to open the gas safety valve. Symptom: glowing igniter, never lights. Spec is 3.2–3.6 A.
Fix: Replace OEM igniter, amp-clamp verify.
Typical all-in: $285–$385 all-in
What it is: Sensor reads out of range. Oven preheats forever or runs hot. Confirmed by sensor resistance check.
Fix: Replace OEM sensor, verify 1080 Ω at 70°F (or model spec), confirm accuracy at 350°F.
Typical all-in: $245–$345 all-in
What it is: Lock stuck closed after self-clean = oven won't release for bake. Or lock won't engage and the board blocks bake / clean as a safety. Common on NE / NX self-clean ovens.
Fix: Replace OEM door lock motor assembly, verify lock engage / release.
Typical all-in: $285–$385 all-in
What it is: On Flex Duo split-cavity ovens, the divider sensor reports temp for both cavities — a bad sensor or a board fault freezes one cavity at low temp. Confirmed in service mode.
Fix: Replace OEM divider sensor or main control board as confirmed.
Typical all-in: $385–$485 all-in
Diagnostic order
NE / NX = standard oven. Flex Duo = split-cavity (extra divider sensor). Chef Collection = built-in. Gas suffix often -K / -T.
E-0A / E-0E = sensor. E-08 = lock motor. SE = stuck key (not heat-related).
Pull racks; visible break or no glow on preheat = element.
1080 Ω at 70°F. Off-spec = replace.
3.2–3.6 A within 60 sec. Weaker = replace.
FAQs
On electric, the bake element has burned open or the oven sensor drifted. On gas, a weak igniter that glows but won't pull enough current to open the safety valve. Repair $245–$485 all-in.
E-0A is an oven temperature sensor open / out-of-range code. The board can't trust the temperature reading and shuts down bake. Sensor replacement runs $245–$345 all-in.
Door lock motor stuck closed after the self-clean cycle. The board sees the lock engaged and blocks bake as a safety. We replace the lock motor assembly and verify cycle. $285–$385 all-in.
Yes — NE59 / NV51 / NX58 Flex Duo split-cavity ovens. The divider sensor is the extra failure point — bad divider sensor makes one cavity behave like it's not heating. We carry the OEM divider sensor on the truck.
$245–$485 all-in. Bake element $285–$385, sensor $245–$345, igniter $285–$385, door lock $285–$385, control board / divider sensor $385–$485. The $149 trip fee credits to repair.
Yes — bake elements, oven sensors, igniters, door lock motors, divider sensors, and main control boards for NE, NX, NV, Chef Collection, and Flex Duo Samsung ovens.
